Communication and control through electrical signals

Communication and control through chemical signals called hormones

Regulation of body temperature through sweat

Digestion and absorption of nutrients in the intestines

Produced by fat cells; controls appetite

A hormone that increases hunger

A type of protein found in muscle cells

A neurotransmitter that regulates mood

Produces insulin and glucagon; has both endocrine and exocrine functions

Produces bile and aids in digestion

Regulates blood pressure and fluid balance

Filters blood and produces urine

Stores and releases ADH and oxytocin

Produces insulin and glucagon

Regulates metabolism and energy levels

Controls heart rate and blood pressure

Secretes cortisol and aldosterone

Secretes epinephrine and norepinephrine

Produces insulin and glucagon

Releases growth hormone and prolactin

Stimulates thyroid to produce thyroxine

Inhibits thyroid hormone production

Regulates calcium levels in the blood

Stimulates adrenal gland function

Gland is activated by hormones from another gland

Gland is activated by nerve impulses

Gland is activated by environmental changes

Gland is activated by nutrients in the blood

Gland is triggered by nerve impulses

Gland is inhibited by nerve impulses

Gland releases hormones in response to temperature changes

Gland functions independently of nerve impulses

Produces melatonin, which controls sleep and wake cycles

Regulates blood sugar levels

Controls heart rate and blood pressure

Aids in digestion and nutrient absorption

Regulates the body's metabolism

Master gland; regulates other endocrine glands

Produces insulin for blood sugar control

Controls the body's immune response

Too little hormone is produced

Too much hormone is produced

Normal hormone levels are maintained

Hormone levels fluctuate excessively

Lowers calcium levels in the blood

Increases calcium levels in the blood

Stimulates bone resorption

Inhibits vitamin D synthesis

Too much hormone is produced

Too little hormone is produced

Normal hormone levels are maintained

Hormone levels fluctuate excessively

Stimulates adrenal glands

Inhibits adrenal glands

Regulates blood sugar levels

Promotes muscle growth

Secretes cortisol and aldosterone

Produces insulin and glucagon

Regulates blood pressure and heart rate

Filters blood and produces urine

Mechanism that regulates hormone levels based on current conditions

A process that amplifies hormone production

A system that eliminates excess hormones

A method for storing hormones in the body

Binds to receptors on the surface of the target cell; uses second messenger

Diffuses through the cell membrane and binds to intracellular receptors

Requires a carrier protein to travel in the bloodstream

Is stored in the target cell until needed
